A New Type of Low Loss l4 GHz High Power Combining Network for Satellite Earth Terminals

Abstract: A High Power Combiner is described which provides equivalent performance at l4 GHz to that which is currently available at 6 GHz. This represents an advance in technology which is achieved through the use of: a) TEl13 Dual-Mode Elliptic Function Invar Filters exhibiting Q's in excess of ll,000, b) Precision hybrid power splitters with a balance of 3 dB±.075 dB over the l4.0-l4.5 GHz band, and c) A Thermal Design Configuration which ensures a temperature rise of not more than 30°C at maximum rated power. These Combiners are rated at l.2 kW in transmission and 3.6 kW in reflection. Using these units as building blocks, up to 6 High Power Amplifiers can be combined into a single antenna feeder input. Measured data is presented at power levels of up to l.7 kW.

International Interest Rate Differentials: The Interaction with Fiscal and Monetary Variables, and the Business Cycle

Abstract: Adapting Den Haan's (1996) methodology based on VARs, this paper documents stylized facts about various deviations from international no arbitrage conditions between Canada and the United States. The calculated statistics provide important information about the dynamics of the economic variables that is lost when the focus is solely on unconditional correlation coefficients. In particular, we find that a higher public debt path and slower economic growth in Canada are associated with higher real interest rates in that country relative to that of the US. These results may suggest that international interest rate differentials reflect, at least in part, a risk premium.

Liquidity Constraints in the U.S. Housing Market

Abstract: We study the severity of liquidity constraints in the U.S. housing market using a life-cycle model with uninsurable idiosyncratic risks in which houses are illiquid, but agents can extract home equity by refinancing their mortgages. The model implies that four-fifths of homeowners are liquidity constrained and willing to pay an average of 13 cents to extract an additional dollar of liquidity from their home. Most homeowners value liquidity for precautionary reasons, anticipating the possibility of income declines and the need to make mortgage payments. The model reproduces well the observed response of consumption to tax rebates and mortgage relief programs and predicts large welfare gains from policies aimed at providing temporary liquidity relief to homeowners.

In-situ bioremediation of diesel-contaminated soil in Canada's Arctic territory: a case study at the Whitehorse International Airport, Yukon Territory

Abstract: Effective remediation of petroleum-contaminated soils in the Arctic is becoming increasingly important as the magnitude of environmental risks becomes better defined. Unfortunately, some of the solutions implemented in southern Canada are too costly to use in the Arctic. However, effective remediation is still necessary. Consequently, traditional techniques are employed, such as excavation and landfarming, which are disruptive to the immediate soils, permafrost, and the surrounding habitat. These remedial methods, however, are becoming unacceptable to First Nations people in some Canadian Arctic communities. This paper describes preliminary results from an in-situ biodegradation study of petroleum-contaminated soils. This technique has the potential to provide an easily applied effective solution to the problem of devising a low cost and uncontroversial method of remediation. Based on bench-scale laboratory feasibility studies, it has been determined that the zone of contaminated soil at the Whitehorse Airport is suitable for in-situ bioremediation application.

A split-beam echo counting model: development of statistical procedures

Abstract: Mulligan and Kieser (1996) (ICES ICES Journal of Marine Science, 53: 403-406) proposed a split-beam echo counting model that addressed the problem of non-uniform detection probability combined with non-uniform fish density over the beam cross- section. To apply the model to real data, statistical procedures to estimate three-dimensional density functions, to estimate kernel density smoothing parameters from the data, and to estimate a data-based smoothing parameter for kernel regression have been developed. In addition, a method to select echoes from individual fish that have been accurately tracked by the automatic tracking algorithm is described. The performance of the model was tested using data from a simulation program and from an experiment that compared acoustic estimates with visual counts of migrating salmon.
